There still continues to be ignorance (and denial) about the complexity of Aryan migration from the Eurasian Steppe to Europe, Iran and India.
I see people (mostly Indians) still getting sentimental about an outdated "Aryan Invasion theory" and drawing support against it from online articles written by other Indians of a similar mindset.
I would ask people to set their biases aside and take the time to educate themselves on the topic.
@Notthedarkweb is correct. The Kurgan hypothesis best explains the migration of people over time, the spread of language from PIE and attempts to explain similarities (and differences) across a large geographic area over a long period of time. Look it up. A few years ago, Asko Parpola wrote a good book on the roots of Hinduism. Read it, if you can.
Data and the scientific method are your best tools to get as close as possible to the truth. Indian swamijis and wannabe historians do not qualify. No one is grinding a political axe here and there is no Western conspiracy. The proposed homeland of the Aryans is the Eurasian Steppe and not Western Europe.
